Q1. In guinea pigs, black (B) is dominant to brown (b), and dolid colour (S) is dominant to spotted (s). A heterozygous black, solid-coloured pig is mated with brown, spotted pig. The total offspring for several litters are black solid=16, black spotted=5, brown solid=5, and brown spotted=14.
Are these genes linked or unlinked? If they are linked, how many map units are they apart?
Q2. Most people with Broca’s aphasia suffer from partial paralysis on the right side of body. Most people with Wernicke’s aphasia do not. Why?
